Application January 13, 1951, Serial No.. 205,931.

The present invention relates to a liquid trans-` fer device and more particularly to a novel fuel spout assembly for a can or container for quickly and. safely dispensing or transferring liquid, such as fuel for van outboard or other motor or power unit, from a supply or delivery can or container to themotor or power unit. Y

Various types and. constructions of dispensing or liquid. transfer devices have been designed, but these have had various objectionable features, not only from the standpoint of their complexity of design and difficulty and cost of manufacture, but also from the method and manner of operation. Although the invention is not limited thereto, it has been illustrated as especially adapted to deliver or transfer liquid fuel to the supply tank of a motor, and it will be readilyappreciated that when refueling a motor after the latter has been in operation for some time, great care must be taken to assure safety rinthe refueling operation by preventing spillage and leakage of the combustible fuel upon adjacent parts ofthe hot engine, and the escape of inflammable vapors.

The presentl invention obviates all of the objections of the prior devices and provides a liquid transfer or pouring spout for dispensing and transferring fuel in a novel and positive manner from a delivery or supply 4container to a fuel or other tank whereby the operator is assured of maximum safety in its use by'reason of the novel means and manner o'f'sealing and positive control of flow whereby all danger of spillage or leakage when the device is inverted is eliminated.

Further objects are to provide a construction of maximum simplicity, efciency,=economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the construction, combination and arrangement of parts illustrated in the accompanying draw-ings, and while there is shown therein a preferred embodiment, it is to be understood that the same is'susc'eptible of modification and change, and comprehends other details, arrangements of parts, features and constructions without departing from the spirit of the invention.

In the drawing:

showing the relative position of the relatively movable parts when the spout assembly is being inserted intol the neck of the fuel tank and before the parts are in feed pouring orA transferring position. f y

Fig; 3 is a view in side elevation but on a greatly reduced scale showing` the assembly in its upright and inoperative or closed position and attached to the neck of the usual pouring spout of a fuel delivery or dispensing can. l Figui is a view in horizontal cross section taken 1n a plane represented by the linev4-4 of Fig. 1.

In thev drawings (Figs. l and 2) and in the following description of the present invention, the pouring spout or'nozzle assembly is disclosed in its inverted position and inserted in the opening in a tank or receptacle for pouring or transferring liquid, such as gasoline or other liquid fuel, to the fuel tank of a motor or combustion engine which requires frequent re-fueling, but it isto be understood that the present device is detachably Y mounted upon the pouring neck of a delivery or tsluplply'can for supplying the liquid fuel to the Referring to the disclosure in the drawing and more particularly to the illustrative embodiment thereinzshown, the `novel spout assembly for the transfer of fluid and especially gasoline or liquid fuel, from. one container to another, comprises a 'v neck vl2 of a tank or other receptacle I3 to be supplied with the fuel. In the illustrative yembodiment, such a'tank or receptacle is shown as the fuel tank of a combustion engine or outboard motor, but it may be any tank or receptacle to be supplied with the liquid or fuel being dispensed. This pouring spout comprises a'spout' member i4 upon which is telescopically mounted a sleeve I5 having a cup-shaped or enlarged upper end I6, and an encompassinglsleeve l1 of a rubber-like resilient sealing materiai unaffected by the vuuid the fuel tankofv a motor or fuel being dispensed and having its upper inturned end I8 anchored over the end of the cupshaped enlargement I6 on the rigid sleeve I5.

The resilient sleeve I1 provides a exible cover for the discharge end of the nozzle or spout assembly that prevents damage to the adjacent or abutting surface and the threads of the tank or receptacle to be supplied with the dispensed liquid fuel. Frequently, such tanks are of a relatively soft or light kweight metal, such as aluminum, which may be readily damaged by a metal to metal contact and the weight of the lling or supporting can and its contents to which the assembly is attached.

Disposed within and projecting substantially centrally through the pouring spout I4 and into the interior of the supply or, delivery can vI 9 (Fig. 3) is an air vent tube 21') having its lower curved end 2| projecting laterally through a longitudinally extending slot 22 in the outer or lower end of the spout I4. This laterally projecting end 2I extends through and is anchored in aligned transverse or radially extending openings inthe encompassing sleeves I and I'I telescoped upon and longitudinally moveable with respect to the spout I4. A cap 23 (Fig. 3) formed of a rubber-like .resilient material is adapted to be snapped over and form a tight enclosure fory the open pouring v end 24 of the spout I4 and the encompassing ends .and held in fixed position upon the air vent tube bya pair of spacers 21, 2l (Fig. 2) press-fitted or otherwise suitably secured upon the tube, one of which abuts the enlarged upper end of the Vsealing plug and the other disposed within the hollow or recessed portion 2B of the plug and seating against the base of the recess, whereby the sealing plug or valve is secured to and movable with the air vent tube and the outer metal sleeve I5 and resilient sleeve I'I.

Aixed to the screw cap I9 is ya guide bracket and support 29 in the form of diametrically spaced bars provided at one end with an annular inverted cone-shaped base 30 conforming to and adapted to v receive and secure the upper end 25 of the pouring spout member I4. Secured to this guide bracket and support is a transverse retainer plate 3 Iv provided with an opening 32 through which projects the air vent tube 20 and by which this tube is guided in itsV longitudinal movement. Mounted within the confines of the guide bracket is a cylindrical iilter screen 33 having an end plate 34 abutting the retainer plate 3I, and within the lter screen is a coil spring 35 encompassing at one end a depending annular flange 35 defining the opening 32 and at the other end the reduced neck 31 on the upper surf-ace of the adjacent spacer 21. This spring is held under compression between the plate 34 and the spacer 21 for spring-biasing the valve plug 26 to closed position.

An air relief valve 38 is provided to present the supply or delivery can i9v from being damaged by internal'pressure.l This valve comprises a ball 39 and coil spring 4B in the cylindrical housing of the valve for. controlling 1F11@ ,110W

4 through a relatively small opening 4I in the cap i0 and a relatively small opening 42 in the circumferential wall of the housing of the relief valve. A screw 43 seating against an end of the coil spring permits adjustment of the pressure at which the relief valve opens. This permits the novel spout assembly. or device of the present invention to be used with any gauge metal supply or delivery can and the relief valve may be adjusted for any desired maximum pressure.

Upon the upper or inner end 44 of the air vent tube is mounted an air valve housing 45 in the form of a hollow sleeve-like member which is preferably internally threaded at one end to receive the threaded upper end 44 of the air vent tube. At its upper or inner end the housing 45 is internally threaded to receive a threaded valve plug 46 provided with a valve seat 4l against which is adapted to seat an O-ring 48 carried by a conical enlargement 45 on the lower or inner end of an air valve 5I. This air valve is provided `with a valve stem 52 o f lessdiameter or cross section than the longitudinal opening or bore'in the valve plug 45 whereby to permit the passage of'air therethrough and through the air vent tube 20 when the valve seat 4l is uncovered by depressing the stem of the air valve 5I.

. Normally, this valve 5I is spring-biasedto closed position by a coil spring 53 seating at its upper or inner end against the valve plug 45 and at its lower or outer end encompassing the end 44 of the air vent tube 2U and seating against a shoulder in the hollow of the air valve housing `45 about the upper or inner end 44 ofthe air vent tube. To actuate the air valve 5I, there is'provided an air valve control bracket 54 mounted by means 0f its lower bracket arm 55 upon the upper threaded end of a rigid supportingrod 56, the lower threaded end of this rod being securely mounted in the retainer plate SI by nuts or other securing means. Y

The lower bracket arm 55 is provided with an opening or aperture for vreceiving and guiding therethrough the air ventV tube 20 as it is moved longitudinally, and the upper bracket arm 5'.' provides an abutment against which the stem 52 of the air valve 5I abuts to unseat `this valve when the air vent tube 20 is elevated or moved longitudinally or inwardly of the pouring spout member I4; i..e. when the sleeve l,I5 and its encompassing kresilient sleeve Il are inserted into the opening in the neck I2 of the fueltank I3 and the sleeve II abuts or seats upon this' neck so thatthe weight of the can I9 and its contentsforces the pouring spout downwardlyrfrom the position of v' Fig.V 2 to the pouring or dispensing position of ,or supply can I9 containing the fuel or other liquid to be dispensed. When the can is in an upright position as inV Fig. 3,v it will be evident that the parts of the present novel assembly are in the relative positionv shown in Fig. 2 except 'that the spout, assembly will be in upright instead of its inverted position as there shown, with the bracket 54 and the air valve 5I depending into the can I9. In this position the valve plug 26 is in its closed position and the air valve 5I "controlling iiow through the air vent tube 20 is also closed',` so that there is no danger of leakage or spillage of the contents of the can. The air relief valve 38 may be adjusted for any maximum adapted to open into the interior of the receiving receptacle during the pouring operation and its inner end projecting into the interior of the supply container, and a valve for controlling ilow through the air vent, said valve and valve plug being carried by the air vent tube and the latter carried by the concentric sleeve whereby said air vent tube, its valve and the valve plug are movable simultaneously upon relative movement of the concentric sleeve with respect to the pouring spout.
